Let's say there was an infamous Internet Troll on your user forum -- you know the guy.
He posts inflammatory comments about your favorite political leader only to cause you emotional distress.
He makes outrageous or absurd statements intended to frustrate you.
He deliberately posts off-topic comments.
Would you wish this Troll a Happy Valentine's Day? Even if you knew that he has no concern for your ego-driven desire to validate your meaningless existence?
